The Dualshock Hardware
The DualShock 4 displays the same general layout and buttons as past DualShock controllers, but now the controller offers additional features along with new buttons. The most obvious change is the inclusion of a wide touchpad where the Select and Start button were; those buttons are now replaced with an Options button instead. Sony has mentioned that the touchpad can respond to up to two fingers at a time, which expands the number of possibilities for input to those like you would see on a smartphone. In addition, the DualShock 4 sports a 3.5-mm headphone jack that supports surround sound along with both an accelerometer and a gyroscope, both reported to be better than what is currently included in the DualShock 3 and Vita. The two rumble motors can now have varying strength, a change from the DualShock 3 where rumble was either active or not. This will create a heightened sense of realism in all PlayStation 4 games. The DualShock 4 also includes a built-in speaker, meaning that sounds from the game can play through the controller instead of your normal speakers.
